I have a difficult time associating pain with flora. Unless the pain is you feeling a loss because the tree was cut down. If that's the case, I think most DPCers will not stretch that far.
I do not think the tree felt pain. I'm not sure how to help with this one. Maybe numerous trees in the same manner, as a pain to the environment or something, but one tree seems to be stretching it for this challenge.
Ok. I'm sure you are hearing that the picture is too small, BUT, the subject is nice and big, so you can see what you are trying to convey. And you can tell that the subject is in focus. Good luck.
When you enter a challenge, remember it is about competition and one of the things you should avail yourself is to present the images in the alloted size. While the concept is nice you did not take advantage and the voters will cast your effort aside. I am voting as if the size was bigger but do not be surprised if you voted down by many.
